Synchrotron Radiation

Definition

Synchrotron radiation is the electromagnetic radiation emitted when charged particles, such as electrons, are accelerated radially, particularly in a synchrotron or storage ring. This radiation is significant in various high-energy applications and plays a crucial role in understanding the behavior of matter under extreme conditions.
